DISKCUTTING MACHINE.

Specification of Letters Patent.

Patented Apr. 15,1913.

` Application led February 17, i1912. Serial No. 678,313.

To all whom it may Gomera Be it known that l, SAMUEL C. Bonn, a citizen of the United States, and Aa resident ot llollyoak, Newcastle county, State of Delaware, have invented certain new and useful Improvements in l)isl\'-( lutling Machines, ot' which the following is a specification.

My invention relates to improvements in machines 'for cutting disks troni a cylindrical rod, and more particularly to iniproreinents .in n'iaellines ttor cutting a cylinder or rod of cork, or analogous material, transversely into disks oi a predeterniined thickness.

My invention in its preferred tiorin conn prises a suitable pedestal the top o'l which carries bearings for a shaft which carries at its center a driving` pulley and at its ends circulaiknives; of two oppositely arranged of rotating carriers for the rods which are to becut into disks; and ot suitable means for rotating' these carriers to bring the rods successively to the knives and for advancing a rod between successive contacts with the knife a predetermined distance to torni a disk of the desired thickness.

ln the accompanying drawings forming part of this specification and in which simi lar letters of reference indicate similar parts throughout the several vicwszmlfigure l, is a side and Fig'. 2, a trout elevation o'l my disk cutting machine. Fig. 3, an enlarged section through the carriers ttor carrying the rods to be eut to the circular knives, this section being,` upon the line A--1\, Fig. 1;'

Fig'. 4, a plan of that part of the machine included between the inner ends ot the rod carriers; Fig. 5, a section of Fig. 3 on line .Bf-BL lis a pedestal the top of which carries a frame 2 which carries bearings 3 tor a shaft et.

5 is a pulley upon shaft 4 which may be driven by a belt in the usual manner.

6 are circular knives carried by the opsite ends of shaft 4. At the top of the pedestal 'l are two circular statioi'tary plates 7 the respective pewmipheries of which are threaded in opposite dnections and each of'whieh is carried` by a eentralstationary splndlet which carries '.LOtfttingwheads Q-lthwhioh carry` :tixedly are passed one into each tube .l1 and are each one ,gripped between a worin wheel 13 and a pulley 14. As the heads 9-10 carrying' the tubes ll are rotated around the spindle S the worm wheels 13 will, for each complete revolution oit the heads, be rotated by the teeth, upon the periphery of the platesl 7 a distance equal to the pitch of the threads on the plates and the rod. will be advanced during each complete revolution of the heads this distance. As cach of the rods is brought into operative contact with the circular knives once during-each revolution ot the heads 9-10 the pitch of the'threads upon the periphery of the stationary plates 7 determines the thickness of the disk to be cut. For instance, if it be desired to produce disks of 3/32 inch thickness the threads upon the plates 7 would be 3/32 inch pitch. A

The circular knives (i and the heads 9--10 carryingthc tubes 11 which carry the rods 15 rotate in opposite directions and as both oi.' the ciieular knives G are carried upon the saine shaft and rotate in the same direction it follows that both of the sets of heads 9%10 rotate in the saine direction, but as the rods carried by the tubes carried by the heads 9-10 on opposite sides of the ma ehinehave to be i'cd to the center of the machine the worin wheels 13, which in conjunction with the idlers llt, carried by opposite heads have to be driven one right and the other left, hence the peripheries of the stationary plates 7A are threaded one right and one leitt.

.The 'feeding o lf the rods through thc tubes Vll is slow but continuous, and in order that the rods after being: cut by the knife shall noteontact with the knife, to the injury ot both o't them, until a complete revolution ot the heads tlv-v10 has been aeconiplishci'l, the

spindle 8 aroundlv'vhich these heads turn is s ightlyv out of the horizontal, its outer end being somewhat lower than its inner end.

y this construction the inner ends of the tubes l1, `and the heads 7 which carry these tubes, areslightly out of parallel with the knives 6, the upper paits of the heads being at a greatera distance 'from the knives than the' lower parts. The inclination is slight but suilicientto insure that the end ofhthe rod after having been operated upon by` the 'knife will not be moved into engagement with the side of the knife While these parts are in position to permit such an accident.

In a fast moving machine of this description.

somearrangementv of this kind is necessary toprevent the side 'of the knife from tearing the end ofthe rod or causing burning or" the latter by the heat that would be developed by a frictional contact between the end of the rod and the side of the knife.

While I- have shown and described'a inachine furnished with two oppositely placed heads it Will, of course, be understood that either olie of the heads'may be dispensed with' if desired.

The worm Wheels 13 and the idle'rs 14 are,

` as has been before stated, arranged in pairs,

that is ea'ch tube 11 isfurnished at its inner end, or in line ,with its inner end, With a Worm Wheel and idler to iteed the rodto the knives.- A convenient means for carrying the Worm Wheel and idler consists of a fra-me i6, rigs. a and 5, which is furnished with a stem 17 which` is adapted to-be driven into a corresponding hole found in 'the webs of the' pulleys 12', the inner ends of the tubes 1l being let 'into opposite sides of these vwebs and registering with the perforations 18 in'these frames.' The outer parts of the frames 1G carry ears 19 for carryingthe pivots 20-2l Whichi carry respectively, 'the Worm wheels 13 land idlers le as shown:

While have described my invention as a machine for cutting disks from rods itwill be understood that` it can vas Well be used to cut a tubetransversely into Washers of prodetermined thickness.

Having thus described my invention I claim as new and desire to secure by Letters Patent l. .InV a machine for cutting disks from cylindrical rods, in combination, a circuler rotating knife, a means for carrying a plu-y rality of rods and for'. bringing them successively into contact with and past the cutting edge of said knife, and a means for continuously advancing said rods through said carrying means.
